How To Mix Fast-Setting Concrete | DIY

Welcome back to Albany County Fasteners,
Fasteners 101. I’m Bob and today I’m going to show you how to mix some
concrete. But before we do that, please subscribe, like, and share my videos and
hit the bell so you get new content warnings. Let’s get started. This is a bag of concrete – 50 pounds. It’s quick-setting concrete. This is what I
selected. They have quick-setting, they have slow setting, you know, many different
mixtures. You can find it at your home improvement store. This is by quikrete.
I did many years of concrete work and many would think that, you know, “it’s a bag of concrete; it’s pre-mixed.” Well there are some important things that you need to know.
Especially with fast setting concrete. Fast-setting concrete sets very quickly,
so you have to have your materials ready before you mix the concrete. I’m
going to show you how to properly mix the concrete. So I poured some of this fast setting concrete into this bucket. It’s a 5 gallon bucket I guess.
You get these at Lowe’s or Home Depot, any of those. One good thing to do before
you put any water in is to make sure you mix the materials around after you
pour it out of the bag. That makes sure that all the materials are nice and loose. Now a couple of tips: If you go to your box store and you buy a bag of this
product and you come back and you have chunks or it’s not fine, bring it back,
get a new bag. Sometimes when they ship these products they’re out exposed
to the elements; they could get hit with water, and then the product starts
to set up which is no good. So I would highly recommend that
you make sure that you have fine product. Now I’m gonna go get some water
and we’re gonna start to mix the product. So I went and got my water. This is cold
clean tap water. Do not use hot water. Hot water will set
the concrete faster, so you want to avoid doing that. It’s a good thing to just pull out of the center here, and pull to the side some of
the concrete and basically just dig a little hole there to pour the water in. I’m going to start to pour this in
then I’m gonna mix it. You want to go a little bit at a time, not too much, because then it’ll become too soupy and then you’ll have to put some more concrete in, which
I might have to do here but I’m just gonna keep mixing it. I’ll probably
need more than what I have here anyway. To do this little project I’m doing. You just keep mixing it. Make sure you get the bottoms and the sides. Because otherwise you’re gonna have dry
pockets with dry concrete. You got to make sure you mix it well. Now I’m using
this ladle, you can also get a battery drill and put a concrete auger on it and
mix it that way. For this I’m just doing it by hand. Make sure you get down to the bottom. You get everything mixed well. I’m almost down there now. Now you don’t want it soupy like it is here. So I’m going to add some more concrete to this but you want to make sure that it’s well mixed. You’re better off when you
have fast-setting concrete that it’s a little more wet because the drier the
faster it’s going to set up on you. I’m all the way down to the bottom now.
Now it’s coming together well. Okay I’m going to add some more concrete. I like to start off more soupy than dry
because it makes it easy to get everything that’s on the bottom. If you’re working on your project and as you get to the bottom and find
the concrete is setting up, because this is fast set, do not add water to loosen up
the product. Throw it out. Start off with a new batch, even if it’s a little bit. Just make sure you put a little bit in there with very little water, sometimes
with cups of your hand or a little cup. Pour the water in as you mix it so you
can finish your project off. It’s a little tip. Always a little bit at a
time. Don’t go too fast because if you put too much in then it’s going to get very
dry very quickly and then you have to put more water in. This is getting perfect
now. Now this is a small batch. You can get a big tub with a hoe and you can mix
it. Break your bags open and put it into a big bin.
We’re almost there. This is getting to the perfect consistency that I want. This is also fast setting. So fast setting, once it starts to get to that consistency, will start to set up pretty quickly. Just a little bit more. Not much…I think this is gonna do it. Yep.
Now you can see it. That’s what I’m looking for. Okay. I don’t see any dry material. You want to make sure you have nothing dry.
You want to make sure it’s thoroughly mixed and always wear protection. You
need gloves. You should have a mask on, so you don’t inhale this stuff. It’s not the
greatest stuff for you. Concrete has lime in it. You need to
protect your skin from it because if you use it many, many times,
it also can do some damage to your skin. They don’t tell you that typically but
you learn that over the years. So here we are. Looks good. Just found a dry spot there. But I think I’m good for my little
project. That’s the perfect consistency that I want. It’s not too watery but it
is nice and chunky and thick. This will set up pretty quickly once I put it
into the product that I’m trying to develop here for my next video. A piece of concrete that is already
setting up and then you pour a fresh batch on top of that, they call that a
cold joint. That’s where you’re going to have a possible break and you will see a
joint in the concrete. So you kinda wanna-when you’re working with concrete-you want to move fairly quickly. Especially fast setting. Slow setting,
normal setting, you know it’s much more easier to work with.
I would highly recommend that, if you haven’t worked with concrete before. if
you have a bag and you have extra material, it’s good to roll this up, take
it, put it in a plastic bag like so. Seal it up tight. Make sure you don’t have any holes in the bag because once you break that paper bag open moisture in your
garage or your basement will start to penetrate the concrete and then when you
go to use it let’s just say two months three months, this will prolong the life.
If it’s over a year old chances are that you’ll come back to this and it will be
chunky. You just need to throw it out at that point. A final tip: cleaning. Do not
clean concrete buckets out in your slop sink, your toilet, your regular sink in
your house, your bathtub, don’t do it. Clean it outside. Get a hose, clean the
concrete out in your grass somewhere that you just don’t want to see it.
Though it will leave a residue around. If you clean it out in your sink,
slop sink, toilet, or your bathtub, the trap in the plumbing will collect the
concrete sand and it will set up in there and the end result is it will
reduce the amount of flow of water and whatever else is in there by a
substantial amount. Thus clogging your sink eventually. Hair
will cling to it. A lot of people do this. It’s a big
mistake. Don’t do it. That’s how you mix a bag of concrete. I probably used about 75% of this bag. Thanks for watching. Leave me some comments. Give me your thoughts. I can pour it if I want to but it’s
just easy for me- It’s on here, it’s not gonna come out.

  1. Good…. Thank you

  2. Another tips breath deeply and switch the hand 🖐

  3. Thanks for all the helpful tips. I wish I would have watched this one a few years ago-before I dumped the unused material down my laundry sink drain.

  4. Please do not forget to use a dust musk.

  5. if fast setting quikrete is setting too fast for your application, can it be mixed with regular quikrete to slow down the setting?

  6. very good video
    thank you👍

  7. He also forgot to mention before you start mixing make sure you wear your nice church clothes and shoes and your $400 iPhone watch 😉

  8. hi sir i m from india how to fast set cement concrete ..?
    any chemical name sujest me..thx

  9. I'm making a little patio and I have exactly the same stuff he has, do I need to flatten the ground or measure the floor or anything? I already digged a hole

  10. Americans do it wrong

  11. Oh I forgot to put new clothes on

  12. I'm covering the brick surround of a fireplace which is approximately 12" above the firebox opening and plan to extend it up the wall to the ceiling. Does concrete adhere to plaster? (the walls of the house are plaster)

  13. Clearly you haven’t any experience mixing quick set concrete. The more you mix and add water the more it takes away its quick setting ability. If your going to do an application that requires a concrete consistency like that then save some money and just buy the 60lbs slow setting. If you need quick set to set quick then follow the instructions on the bag it works very well sets very fast … too fast to be trying to mix it.

  14. Im a rookie at this and thank you for the tips learned alot from this video

  15. Very nice video 👌 thank you.

  16. thankyou for the video but it had 2 unskipable adds

  17. I’m pooring a new pad for my AC condensor unit outside tomorrow… i was hoping to just mix buckets and dump em in the “box”, as i make em, say about 7-8 buckets. Can i do that if its slow setting? I’ll be using the cement drill bit on a corded drill.

  18. Granddud don't know perfect ratio to mix concrete 😃 He waste approx 20lb cement to creat 1 Square foot concrete! Best of luck!!

  19. This isn't the way I would do it, if mixing in a bucket I's always add the concrete to a bucket of water.

  20. I was going to say the same thing. Also thanks for telling us where to buy a bucket..never could have figured that one out. You made a simple job look very hard. Maybe try adding more water next time to start…lol!

  21. Thanks for the vid. I followed the instructions on the bag and they warn you about using to much water. I used the instructed amount plus alittle more and I think my mixture was too dry. doohhhhh.

  22. Avoid hauwt wautah.

  23. Thank you. It will help me in my coming project. Much appreciated.

  24. You looked like a guy working by the hour.

  25. Former Army Corps of Engineers. This guy knows his stuff.

  26. nice shoes for concrete work.

  27. Isnt this product made so you don't mix??? Your just supposed to add the water on top and leave

  28. Use a wheelbarrow and a hoe y’all it’s easier to mix than using a bucket

  29. Can I eat it?
    Asking for a friend…

  30. Exactly the help I needed! Thank you!

  31. Thanks for your advice!

  32. I'm planning to put concrete in a hole that was dug too big for a clothes line pole. Will this work?

  33. Quikcrete's own video says you DON'T need to mix it for post holes. Pour the dry mix in, add water, wait 4 hours. Done. Of course, they also say you can mix it first if you want.
    I watched my landlord install a wood fence using the fast-setting stuff. He did all the mixing in the hole with his gloved hand instead of using a bucket. He spent only about a minute stirring it up, then put the post in. The next day every post was rock-solid.

  34. Why not shave that little bit of hair on top of your head?  It really doesn't do much.

  35. How to mix without planning amount needed or relaying water ratio. Useless.

  36. This helped. Thank you!

  37. Maybe a mask should be warn ?

  38. Thank you needed This as a woman to understand I understand this perfectly thanks

  39. Thanks, Bob, I just used your video and all is good!

  40. Perfect. One of my wooden fence posts has loosened up in the ground. I was going to refill the new space around it with more concrete.

  41. For some reason I like people pouring concrete on the ground. :/

  42. Can Quikrete be used to build a brick wall?

  43. This dude sucks at mixing up cement. First you add the mix to water not water to mix. Second it’s around 1 part water to around 4 to 5 parts mix.
